Abstract
System and methods are provided for performing white balancing of an image. An image including one or more pixels is received, wherein a pixel corresponds to an input color value. A light source of the image is determined based at least in part on the input color values of the pixels, wherein the light source is used for illumination when the image is captured. New color values of the pixels are generated to reduce color distortion caused by the light source of the image.
